Reply To: Epik – Exclude Categories on Home Page

I found this from a tutorial. Try adding this to your functions file and replace -1 with the categories you want to exclude –

/** Exclude certain category from posts */
add_action( 'pre_get_posts', 'be_exclude_category_from_blog' );
function be_exclude_category_from_blog( $query ) {

    if( $query->is_main_query() && $query->is_home() ) {
        $query->set( 'cat', '-1' );
    }
}
